....presence information in a CHUM network [4] Peer to peer media streaming is one of the interesting topics in peer to peer computing on the Internet. Tran, et al. 8] focused on reducing the end to end delay of media streaming from a single source to multiple clients on the Internet. The authors in [9] study the assignment of multiple streaming sources with different outbound bandwidths to one requesting peer. There are several challenges to develop multimedia chumcasting. First, CHUM networks must be formed and effective delivery mechanisms must be used to distribute data to peers within CHUM. ....

....27] storage [12, 28] and multicast [9, 1, 32] we in this paper focus on P2P real time media streaming. Different from general P2P file sharing, P2P media streaming poses more stringent resource requirements for real time media data transmission. However, as first addressed in our earlier work [33], for a media file of playback rate R 0 , a single sending peer may not be able or willing to contribute an outbound bandwidth of R0 . Moreover, downloading the entire media file before playback is not the best solution, due to the potentially large media file size and thus long download time. As ....

.... In filesharing systems, a client first downloads the entire file and then uses it, termed as the open after downloading mode; while in media streaming systems, a client consumes the content of a media file while the file is being downloaded, termed as the play while downloading mode [1]. The large volume of media data along with their stringent timing constraint poses challenges for P2P media streaming, which is even exacerbated by the dynamic nature of P2P networks: a peer can get online or offline at any time. Furthermore, a single peer sender may not be able to contribute ....

....peers, the service provider can achieve a large system capacity with a relatively small initial investment. A peerto peer architecture has the potential to provide the desired large scale media distribution service. There is a difference between a file sharing system and a media streaming system [12]. In file sharing systems, a client first downloads the entire file before using it. The shared files are typically small (few Mbytes) and take a relatively short time to download. A file is stored entirely by one peer and hence, a requesting peer needs to establish only one connection to download ....

....involves multiple supplying peers (as shown in Figure 1) each of them streaming a subset of the media data to the requesting peer. To ensure full media quality, the sum of their out bound bandwidth contribution (possibly in different amounts) is at least the same as the media playback rate. In [20], we present an algorithm to assign a subset of the media data to each supplying peer, based on its out bound bandwidth contribution. Our prototype implementation also demonstrates the feasibility of delivering full quality video from multiple supplying peers. 2.2 System Operations k ....

....with a CDN system, nor does it introduce any policy to realize limited and fair peer contribution. In [12] a programming platform is presented to support better implementation of peer to peer multimedia services, including the implementation of our hybrid architecture. Finally, our earlier work [20] solves the problem of assigning media data to supplying peers in a peer to peer streaming session. However, it assumes that the supplying peers will stay in the system indefinitely, and it does not consider the integration of CDN and peer to peer media distribution. 6 Conclusion We have ....
